Bug#264175: why should apt-get -qq update be dangerous?



Package: apt
Version: 0.5.27
Severity: minor

Hi,

apt-get(8) says about --quiet:

|Note that quiet level 2 implies -y, you should never use -qq without a
|no-action modifier such as -d, --print-uris or -s as APT may decided
|to do something you did not expect.

What would be dangerous with apt-get -qq update?

Rationale for this question: apt-get update displays its output in the
order the download servers have reacted in. This is not deterministic
and thus makes it hard to determine whether any changes have occurred.
I'd like to have an option that safely downloads new package files
while reliably creating the same output if no error has occurred.

Greetings
Marc
